Airlines, booking agents, and other flight data creators and distributors publish data related to flights. The flight data is provided to requestors at a time of request about a certain flight, or flight data is provided for a certain group of flights. For example, if a user is searching for flight data about a particular flight or a particular route, the airline system may provide data related to that flight or a group of similar flights, such as flight times, airplane descriptions, airport stops, and price information. Certain requestors are provided data about all available flights or certain groups of flights, such as the current most popular flights. In conventional systems, the flight search systems request the data from an airline system at the time of a user flight search request. Alternatively, in other conventional systems, the flight search systems store current flight data for certain flights and present the current flight data at the time of a user flight search request. However, such flight data is accurate for a limited period of time and may change in the near future.
